Your appearance is one reason. Another is that the gap left by a missing tooth can mean greater strain is put on the teeth at either side. A gap can also mean your "bite" is affected, because the teeth next to the space can lean into the gap and alter the way the upper and lower teeth bite together. This can then lead to food getting packed into the gap, which causes both decay and gum disease

How are missing teeth replaced?

This depends on the number of teeth missing and on where they are in the mouth. The condition of the other teeth also affects the decision.There are two main ways to replace the missing teeth. The first is with a removable false tooth or teeth - a partial denture. The second is with a fixed bridge. A bridge is usually used where there are fewer teeth to replace, or when the missing teeth are only on one side of the mouth.

What is a partial denture?

This is a plate with a number of false teeth on it. It may be all plastic or a mixture of metal and plastic. Both types may have clips (clasps), to help keep the denture in place in the mouth. Depending on where they are, some of these clips may show when you smile or open your mouth.

What is the difference between a plastic partial denture and one that contains metal?

Plastic partial dentures are less expensive to make. But unless they are designed very carefully they can damage the teeth they fit against.Metal partial dentures are usually from an alloy of cobalt and chromium and they are much stronger. They are lighter to wear and can be supported by the remaining teeth. Although the base is metal, they have gum-coloured plastic and natural-looking teeth fixed to them. They are more expensive than the plastic ones.

Q

How do I choose the best type for me?

Be guided by your dentist. He or she will know the condition of your remaining teeth. In most cases a metal-based partial denture gives the best result.

Q

Can I have a bridge fitted straight after having a tooth removed?

In many people it can take up to 6 months for the gums to heal properly after and extraction. This means that you may need to have a temporary denture for 6 months before the bridge is fitted.

Q

Should I take my denture out over night?

Your dentist may recommend removing your dentures at night to give your mouth a chance to rest. If you remove your dentures, it is important to leave them in water to prevent any warping or cracking.

Q

What is the alternative to a partial denture?

The main alternative is a fixed bridge. This is made by putting crowns on the teeth at either side of the space, and then joining these two crowns together by placing a false tooth in the space. This is all made in the laboratory and then the pieces are cemented into place with special adhesives. The bridge can't be removed.Another option is an adhesive bridge. This has wings that are bonded to the back of the supporing teeth with very little drilling involved.

Q

Can I always have a bridge to replace missing teeth?

Bridges are only possible if you have enough strong teeth with good bone support. Your dentist will help you decide which is the best way of replacing missing teeth.

What are bridges made of?

Bridges usually made of porcelain bonded to precious metal. Sometimes, there are other non-precious metals used in the base for strength. There are also new bridges made entirely of a special type of strong porcelain.

Q

How do I look after my bridge?

You need to clean your bridge every day, to prevent problems such as bad breath and gum disease. You also have to clean under the false tooth every day. Your dentist or hygienist will show you how to use a bridge needle or special floss, as a normal toothbrush cannot reach.

Q

Are there other methods for fixing false teeth?

There are other methods, such as using a combination of crowns and partial dentures that can keep the retaining clips out of sight. These are quite specialised dentures, so you should ask your dentist about them.

Q

Can I have teeth which attach to the jawbone?

Yes. By having implants. The success of this technique means you may be able to replace missing teeth without crowning other teeth. See our leaflet "Tell me about Implants" for more details. Remember that it is as important to care for your remaining teeth as it is to replace the missing ones.
